Dear Luggers.....;)
i have been using Squid for a looooooooong time now..;) and alwayz thought it was the answer to all my caching need. Especially as far as Web Caching Solutions/TRansparent proxying has ben concerned for my numerous deployments.
Off late....i have been settin up and running a small isp setup in bombay and have been faced with a small perplexing issue. I have about 100 clients as of now....nd growing day-by-day......
Initially, when the customers were few, the load was miniscule and Squid on the Gateway would doa lovely job. Of late....Squid has been less of a boon and more of a curse to my setup. the memory requirements/cpu hoggin is taking my system down with cpu usage averagin @ 90%......nd due to tremendous requests being bombared @ it, the queue just dramatically increases response times to the clients.
That apart....my Transparent Web Caching solution also implements ad-zapping......which i hav made spawd 15 sub threads for url re-directing under squid.
Due to the huge boggin down of my server...i had to shut down caching.
Is there ny solution....????. Where hav i erred.?????. Should i setup caching on a box different to the billing server..????
Ur comments/suggestions r welcome.

Ok, move squid to a box with lots of small disks. squid is limited in its throughput by disk io, so you toss a box with loads of ram and fast disks (lots of spindles 4 x 9GB SCSI is better than 1 x 40 GB IDE).
And if CPU time is still hogged, then move the box to a 2.2 kernel/FreeBSD

Nope, just use DNS for this. Ads rresolve to 127.0.0.1

Yup, move the billing server to another machine hat is accessibly only via a local CGI (I am asuming a database here). This machine should not be accessible directly from the internet.
Which ISP, BTW?
